There are intelligent conservatives.... they're just not the ones in power in the US right now, and not the lion's share of the people who voted for Trump.
Classic economic conservatism means lower taxes for a wide swath of people, and pushing for lighter regulation while understanding that certain rules are still necessary. Trump is solely interested in tax cuts for the wealthy and wants to deregulate as much as possible, even those rules that maintain basic labor standards, prevent environmental catastrophes and are in direct response to economic meltdowns.
Classic social conservatism means a tendency to cling to both good and bad religious values: it may mean a regressive attitude toward LGBT people, but it also means valuing a basic amount of compassion, fidelity and respect. For Trump, it only means the bad parts: he's happy to strip away basic protections and freedoms for groups the bigots don't like, but he also delights in yanking social programs that likely save lives... and of course, he's the antithesis of the religion that supposedly helped get him into office. It was hilarious/disturbing to see that photoshopped image of Jesus guiding Trump's hand in the Oval Office knowing that these 'virtuous' voters were rooting for a guy who cheated on his first two wives, celebrates sexual harassment, lies on a constant basis and is so greedy that he's more interested in funding his golf course trips than feeding senior citizens.
Unfortunately, you might not see a greater turn toward a better form of conservatism until and unless Trump's administration implodes. We're already starting to see a lot of people who realize they've been hoodwinked.
